Embedded guidance device of autonomous vehicle and intelligent composite guidance method thereof

Abstract

The invention discloses an embedded guidance device of autonomous vehicle in automated transportation and an intelligent composite guidance method thereof, belonging to the field of autonomous vehicle guidance. An image processor, a master controller, a motion controller and an interface controller of the device of the invention are all connected to a CAN bus via an isolation transceiver, the device further comprises a picture pick-up system, an encoder, a memory, a driving system, a human-machine interface and the like. The composite guidance method thereof comprises network path traveling guidance based on radio frequency identification and single path tracking guidance based on visual identification, the former accomplishes path choice and junction turning of vehicle at intersections with multiple marked lines, the latter accomplishes precise movement of vehicle along guidance marked lines and precise location thereof at stop signs. The invention enriches acquiring ways of guidance information, improves processing speed of guidance information and enhances intelligent service ability of autonomous vehicle.

Description

technical field [0001] The invention relates to a guiding device, in particular to an embedded guiding device of an autonomous vehicle and an intelligent composite guiding method thereof, belonging to the field of guiding autonomous vehicles in automatic transportation. Background technique [0002] Autonomous vehicles in the field of automated conveying technology are used to realize the automatic conveying of materials. The guiding method is one of the core technologies for autonomous vehicles to realize automatic conveying. It not only determines the flexibility of the automated conveying system composed of it, but also affects the operation of the system. Reliability and configuration costs. At present, the guidance technologies that have been researched, developed and applied mainly include: embedding electromagnetic induction, laser reflection, track deduction, optical reflection and visual recognition, etc. There are great differences in environmental space condition...

Problems solved by technology

Although industrial control computers can provide a general-purpose development platform and a good man-machine interface, they are not specially designed for image recognition and motion control applications after all. Multiple recognition and control algorithms with large calculations and high real-time requirements are of great importance to industrial control. The performance of the computer and its operating system has brought great challenges, especially in the patent [03111168.8] to perform serial image processing on the running path markings, station address code identifiers and operating status control identifiers, industrial control computers The computational burden is heavier
